The TRANSFORMERS name game.

HI!
Just a little game...
Ok, what you have to do is name something associated with TRANSFORMERS like a character, book, comic, cartoon etc etc which starts with the 3rd letter left from the previous name.
E.G. If i start off with PROWL the 3rd letter is O which means the next person has to name something beginning with O.
so, Optimus Prime
3rd letter being T
so the next person names something beginning with T. and it goes on and on.......

OK lets have a bit of fun and test your Transformers knowledge.....
Also please add pics whenever possible to make it more fun.
Before anyone asks you can duplicate names and there is no prize.
Have fun - cheerz sith.
